Aviation AM Centre qualifies EOS metal 3D printing for certified aerospace parts

The Aviation AM Centre (AAMC), an EASA-approved additive manufacturing production organization based in Düsseldorf, has qualified EOS metal 3D printing technology for use under its EASA Part 21G production approval. The move makes AAMC the first independent AM supplier to deliver certified aerospace components using EOS’s laser powder bed fusion (LPBF) technology.

AAMC’s qualification includes both the EOS process and materials, enabling the production of aircraft components with EASA Form 1 certification. This certificate allows parts to be supplied directly to airlines, maintenance, repair and overhaul (MRO) providers, and suppliers—circumventing traditional original equipment manufacturer (OEM) supply chains and reducing turnaround times for replacement parts.

The certification applies to an AMCM M290-2 dual-laser 1kW system developed by AMCM, a subsidiary of EOS. It supports a range of aerospace-grade metals, including aluminum, titanium, stainless steel, and copper. AAMC reports that these parts will be used in cabin structures and aircraft systems to support ongoing maintenance operations.

“We carefully reviewed and documented every step of the metal AM process under our EASA Part-21G approval to meet the highest aviation quality standards,” said Vinayak Jagtap, Production Manager at AAMC. “As a result, our approval scope has been expanded to include EOS and AMCM metal LPBF technology.”

Bernhard Randerath, Chairman and Accountable Manager at AAMC, said the certification marks a shift from prototyping to full production. “Our licensing model also allows partners to establish their own certified AM production cells and benefit from our expertise and production organization approval,” he said.

EOS Senior Vice President for EMEA Markus Glasser noted that the certification extends to both metal and polymer processes. “The EOS additive manufacturing technology is the first metal AM technology worldwide to comply with the stringent aviation production regulation EASA Part 21G,” he said. “This capability will significantly accelerate AM adoption within the aviation industry.”

AAMC states that its use of metal and polymer AM technologies will help mitigate ongoing supply chain disruptions by enabling faster, more cost-effective production of certified spare parts across a range of aircraft platforms.
